QR code with multibyte characters

[entrepreneur pankti]

Jdev 11.1.2.2.0

I have to generate a QR bar-code for my application and for which I have used zxing by google to achieve the same. It is working well when scanned for text, numbers and special characters. But when I give any other language than English and scan the bar-code, it is displaying every character as a question mark.

How do I achieve QR bar-code generation for multi byte characters.

  What are you using to generate the QR Codes?

  The on-line "QR Code Generator", the command-line interface or probably your own code?

  I've tried the on-line generator and successfully encoded proper non-Latin text:
  https://zxing.org/w/chart?cht=qr&chs=350x350&chld=L&choe=UTF-8&chl=%D0%9A%D0%B8%D1%80%D0%B8%D0%BB%D0%B8%D1%86%D0%B0%0A%E4%B8%AD%E6%96%87%0A%E6%B1%89%E5%AD%97%2F%E6%BC%A2%E5%AD%97

  The command-line one failed to deliver though.

Thanks a lot for your time Sir.

I have followed the below blog for implementing QR code

http://javapapers.com/core-java/java-qr-code/

  Own code than. OK.

  The demonstrative code is not exactly correct. The encoding is being used weirdly.

  Put the encoding in the encoding hints map:

  hintMap.put(EncodeHintType.CHARACTER_SET, charset);

  And instead of:
    new String(qrCodeData.getBytes(charset), charset)
  just supply the text to be encoded:

    qrCodeData

  The core problem is that QRCode only specifies how to encode a subset of the Japanese Kanji text, and has specific mode for Kanji, all other non-ASCII texts must be encoded in binary mode, but there is no specification as to what encoding should be used when encoding.

  UTF-8 is a common sensible default, but is not mandatory.

Thanks sir

I was able to provide qrCodeData instead of that new string statement.

But while tring to replace
hintMap.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L);
with code suggested i.e.
hintMap.put(EncodeHintType.CHARACTER_SET, charset);

I'm getting the error
"put(EncodeHintType,String) cannot invoke put(com.google.zxing.EncodeHintType, com.google.zxing.qrcode.decoder.ErrorCorrectionLevel) in Map"

  Your hints' Map declaration is wrong.

  Hints is Map<EncodeHintType, Object>.

  You're not supposed to replace the error correction hint, but rather add a new hint.

  May I suggest the collections trail in the Java tutorial [1].
